Also not a fan of the duplicates, especially if the "better" one comes second. LH does it and pretty sure VREdging does similar with "director cuts". At the very least the relationship between the two videos needs to be easy to go between the different copies of the same scene -- or ideally be the same scene with different videos attached (same scene link/scene card in the list, same playlist assignments, etc).
I'd also not mind it as much if the longer/better version came first -- otherwise you end up watching the first scene and you're not going to want to exactly find the 7 minutes of differences within the hour of video when the second comes out.
